Defame1297 1d40544075 fix(gates): hold skill versions above main's tip as well as the merge-base
Why: two branches that both bump a skill 1.0.0 -> 1.0.1 with different
content merge without a conflict, and each passed the gate against its own
merge-base, so main could ship two changes under one version.

Implementation Notes:
- check-skill-version-bump requires the pushed version to exceed both the
  merge-base and the main tip; failures name the baseline they missed.
- Presence is read from the tree, so a blob missing from a partial clone is
  a read failure instead of a silently exempt "new" skill.
- A leading UTF-8 BOM no longer reads as a missing version.
- Version parts reject leading zeros in all three validators
  (check-skill-version-bump, skill-size-check, factory-audit).
- New tests cover equal bumps, moved files, major/minor ordering, bad refs,
  unreadable blobs, mode-only changes, symlinks and tag peeling.

Impact: ADR-0022 amended (reverses "not main's current tip"); gates.md
updated to match, including pre-commit 4.6.1's exact ref selection.

# Regression test for scripts/skill-size-check.sh, which enforces two
# independent gate families that must not be conflated:
#
# * agentskills.io spec conformance — 500 lines and a 5,000-token ceiling
# enforced via a word-count proxy (MAX_WORDS, currently 2770) over the
# WHOLE FILE, frontmatter included.
# * ADR-0020 context budget — description 250 chars SUGGESTION / 400 FAIL,
# body-ONLY 600 words SUGGESTION / 900 FAIL, and resolvable boundary-clause
# routing targets.
#
# The constant-agreement block below is the load-bearing part: all three copies
# (this hook, the auditor's skill flow, the auditor's agent flow) are
# hand-duplicated because a cache-installed plugin cannot read outside its own
# directory, and nothing but these assertions stops them drifting.
#
# ADR-0025 merged skill-audit and agent-audit into factory-audit, which moved two
# of those copies but did not reduce them to one: the constants live in the two
# mode libraries validate.sh sources, and the two libraries still declare them
# separately. So the comparisons below read lib-checks-skill.sh and
# lib-checks-agent.sh directly rather than the entry point, which declares none
# of them — grepping validate.sh would find nothing and report every constant as
# <unset>, or worse, silently agree that two empty values match.

# make_tree_fixture <label> <desc> <body_words> — a SKILL.md inside a synthetic
# apm plugin monorepo, so the boundary-target resolver has a universe.
#
# Resolution walks up FROM THE TARGET FILE to an authoring root (the nearest
# ancestor holding plugins/*/.apm/{skills,agents}, falling back to .git); it is
# never derived from the checker's own location, because deriving it from
# ${BASH_SOURCE} leaked this repo's 39-skill universe into every consumer repo
# running the hook. A fixture in a bare mktemp -d therefore has NO universe and
# correctly reports "DID NOT RUN" — that is not a bug to paper over with a
# looser assertion, it is why the fixture has to be a real tree:
#
# <root>/plugins/subject-plugin/.apm/skills/<label>/SKILL.md <- the subject
# <root>/plugins/subject-plugin/.apm/skills/sibling-skill/ <- same package
# <root>/plugins/subject-plugin/.apm/agents/sibling-agent.agent.md
# <root>/plugins/other-plugin/.apm/skills/cross-plugin-skill/ <- sibling plugin
#
# The sibling plugin is what makes "every plugin in the monorepo contributes its
# names" testable; without it a cross-plugin target and a typo are the same.
#
# Both sibling skill directories get a real SKILL.md, and that is load-bearing
# rather than tidiness: a skill directory is a resolvable name only if it HOLDS
# a SKILL.md. An empty leftover directory is untracked by git, so counting one
# made a target resolve on the machine that made it and dangle in a fresh clone
# — the same install-dependence the deployed-tree rule exists to remove. This
# fixture used to `mkdir` the two siblings and write nothing into them, so it
# was itself relying on the behaviour the resolver no longer has.

#
# ADR-0020 records the broken routing targets and splits fixing them into its own
# issue. This asserted the gate actually sees them rather than the check being
# vacuous in the corpus it was written against.
#
# There used to be a third probe here, for `skill-improve` in skill-audit's
# description. It was already stale: that target was fixed, so the iteration
# permanently took a `pass "SKIP: ..."` branch — an assertion-free result counted
# in the totals, which is worse than no probe at all because it makes the suite
# look one test stronger than it is. It also contradicted
# tests/test-adr0020-targets.sh, which pins the live dangling set as EXACTLY
# {neuledge-context}; that file is the authority on the set, this one only
# checks each member is individually detected.
#
# Both SKIP branches are gone with it, for the same reason. A probe whose fixture
# has been retrofitted is not "still passing" — it is a pin that needs updating,
# here and in the exact-set assertion in test-adr0020-targets.sh, and it should
# say so out loud rather than quietly agreeing with whatever it finds.
# The gitea-labels probe was dropped when the issue #99 retrofit cut the
# composition sentence whose YAML fold produced that target. Per the rule above
# it is removed, not skipped.
#
# The `neuledge-context` probe — the last one — went the same way in wave 3 of
# that retrofit, which deleted the boundary clause naming it. **The corpus now
# has zero dangling targets**, so this loop is removed entirely rather than left
# to iterate over an empty list.
#
# That is deliberate and follows the rule stated above. A loop over no probes
# produces no assertion while still returning success, which is the vacuous-pass
# shape this comment block exists to reject — it would make the suite look one
# test stronger than it is, exactly the complaint levelled at the old
# `skill-improve` SKIP branch.
#
# Nothing is lost. This file only ever checked that each member of the live
# dangling set is individually detected; tests/test-adr0020-targets.sh remains
# the authority on the set itself, and now pins it as EMPTY, which is what
# catches a newly-authored clause naming a target that does not resolve. That
# file also carries synthetic fixtures built inside a real plugin tree, which
# exercise the detection path without depending on the corpus staying broken.
#
# If a real dangling target ever reappears, add its probe back here.
